How to enforce password complexity in XAF

This task can be accomplished by validating user-entered passwords in the ChangePasswordOnLogonParameters and ChangePasswordParameters detail views. Here, we create a code rule to check password complexity using a custom function. This rule should be checked in a custom context, attached to the DialogOK action, because ChangePasswordOnLogonParameters is a non-persistent object, and the Save context is not appropriate for it.
Also, we have to explicitly initialize the validation rule set, otherwise validation won't work prior to user login.

For additional information, refer to the Non Persistent Objects Validation help topic.
